operate between the arms of the guide-standards fl so as to guide thccutter-fratrie as a cut is heiner made by' its wire. 'l`he inner end ofeach spindle is formed with ahead 2t), which is provided at its end withan annular flange or disk-like portion 2] under which the cutter-wires22 are passed. These cutter-Wires lie within notches 22% provided in theouter pcripheral portions of the head flanges 2l of the oppositespindles of a frame and have their ends passing inwardly diametricallyacross the inner faces of such flanged portions, the heads 2() of thespindles being cut away, as at 24, for such purpose, and secured tosuitable securing means Z5 on the frame arms. The notch 23 of eachspindle is disposed in the outer peripheral portion of its flange 2lrelative to the associated frame arm and its depth is less than that ofthe radius of the flange, thus positioning the span of the cutter-wireat a greater radius from the cutter-wheel center than is the axis of thespindle 1G and guide-roller 1S, as shown in Figs. 3 and 5. 'lhispositioning of tlre cutter-wires relative to the axis of theguiderollcrs 1S of the cutter-frames causes them to move ilmli'fferentplanes as they descendand ascend between the arms of theguide-stainlards 9, the wire reaching a central point between the armsof a standard when at its limit of downward movement', as illustrated bythe dotted lines .'r-z/ in Fig. 3. In order that the clay column 26shall be given a square cut hy each cutter-wire as it passestherethrough on its descending movement the guide standards J areinclined forwardly at a suffity ient angle to the surface of thecarrier-bars G of the associated carrier-seetions to compensat e for theangle described by the descent of a wire relative to a perpendicularduring the cutting action, thus causing a wire to fol ow a perpendicularplane in its descent through the column and a plane at an angle to thecut end of the column on its descending movement7 which plane of ascentis in substantially the same position relative to the forward guide-armas the plane of descent is to rear guide-arm of a standard, asrepresented by the lines r y in Fig. 3, the dotted line s thereofdesignating the central line of the standard. This feature of myinvent'ion is of special importance to the operation and coi'istructionof In achine of this class due to the fact that a positive guiding ofthe cutter-wires in their descending and ascending movements through theclay-column is effected and the construction of the carrier issimpliiied and lightened. While in my former Letters Patent aforesaidthe cutter-wires have been positively guided in their descending orcutting movements by the action of the guide-standards of' the carrier,there was no provision made for positively guiding the wires in theirascendingr movements after making a cut thereby rendering them liable tohound away from their supposed planes of movement and have contact withthe surface .of the cut block or section Bti next ahead by positioningthe wires as above described so that they have an angular movementoutwardly from the column end as illustrated by the line lt/ in Fig. 3.W'ifth my improved construction the endless carrier is also made lighterdue to the lightening of the guidestandards thereof over thoseheretofore used, thus requiring a less amount of power to move thecarrier and operate the machine, which is of considerable importance inmachines of this class.

The operation of myinvention is as follows: As the cutter-wire of acutter-frame descends through the clav column 26 it is positively guidedby the guide-stamlards 9, the inclination of which is sulicient to(annpensate for the angular movement of the wire relative to aperpemlicular plane duc to its being offset outwardly from the axes ofthe guide-rollers 1S of the cutter-frames, so that a rightangled eut ofthe column will be made. Un the con'ipletion of the cut, thecarrier-section carrying the block thus severed is caused to tipslightly forward due to its passing upon a declined portion of the track2, thus effecting a separation of the colitiguous block ends to form aspace therebetween for the ascending Wire to pass through as shown inFig. 1. As the. Wire ascends, its position relative to thc axes of theinde-rollers 18 causes it to move outwardly rom contact with the end ofthe succeeding block, as indicated by the dotted line y in Fig. 3, butnot sufficiently to have contact with the end of the preceding blockwhereby to mar its surface, and it is positively guided in suchascending movement by the parallel arms of the associated guidestandards9.

Having thus described. my invention, what I claim as new and desire tosecure by Letters Patent, is,

l. ln combination, a revoluble cutterframe having guide-members at itsextremities, a cutter-Wire carried by the cutterframe and off-setoutwardly from the axes of the guiding-members, and an endless carriercomprising a plurality of pivotally connected sections each having aU-shaped guide standard inclined slightly from a perpendicular IIO andadapted to eieet a positive guiding n? the Cutter-wire both in itsdeseeniiing and ascending movements through a eolnnin.

2. In eombinat'ion, a reveluble cutterirame havingr guiderollers at itsends, a vutter-Wire carried by the cutter-frame and disposed at agreater radius from the axis of the cutter-frame than the axes of theguide-.rollers, and an endless carrier comprising a plurality offlexibly connected seetiens eaeh hav ing a U-shaped guide standard ateither end lor cooperating with the guide-rollers, the upper terminalsof which standards enrve outwardl)r to abut the terminal of the standardol' the eontiguous seetion, said standards heine; slightly inclined froma perpendicular to eause the cutter-wire to follow a perpen dieular@ourse in its cutting movement and to move out of Contact with thecolumn end in its ascending movement.

3, In combination a revoluhle cutterfraine, guide-rollers carried at itsextremities, a earrier having guide-standards associated therewith tocooperate With the guide-reliefs of the frames to guide the frameextremities during a cutting and subsequent ascending movennent,i aCutting element carried at the extremities of the cutter-frame andhaving a greater radius than that of the axes of the guide-rollersrelative to the axis of the eutter-frame wherebv the cutting-elementwill have different pianes of movement when making a eut and ascendingtherefrom.

4. in combination a revoluhie cutteriraine, guide-rollers Carriedthereby, a nutten wire carried by the cutter-frame and having a greaterradins than that oi the axes of the guide-rollers relative to the axisof the eutter-fraine, and a carrier having members For cooperating withthe guide-rollers of the frame to guide their Cutting and subsequentaseending movements, said nienihers heilig slightly inclined from a.perpemiienlar reliative to the earrier wherel'lv to ranse theeutter-wii'e to have a perpelulieular cutting movement and an angledaseending movement alter a eut.

5. The ennnbinatinn with a Carrier having guide-standar(is inclined froma perpendieie lar relative to the attaehed carrier-section, ol

a revolnble cutter having a piurality of at-V tached cutter-frames eachcarrying a cutterw'ire and guide-rollers 'for cooperating with theguide-standards of the carrier, said eutter-Wires having dillerent radiithan the axes of the gnidemollers relative to the axes of the (stutter,Wl'ierehy the eutter-wires have anguiar descending and ascendingmovements when nia-king a eut.

6. The eornlnation with a carrier having guide-standards provided withspaced parallel guide-arms, of a revoluble cutter earry inq a pluralityof U-shaped entier-frames, a spnide lined at the end of eaeh freine armand having its inner end formed with a flange provided with an outwardlydis )esed notch the depth of which is less than the radius of the iange,a guide-roller carried by eaeh spindle to cooperate With theguide-standards of the carrier, and a cutter-Wire spannin r eacheutter-i'rame and engaging the note ies in the associated spindleswhereinr it is offset from the axes of the guide-rollers, substantiallyas described.

In testimony whereof i have hereunto signed my naine to thisspeeiieation in the l presenee of two subscribing Witnesses.
